Harbor River Bridge - Slated Replacement
Posted March 28, 2016, by Patrick McBriarty (patrick_mcbriarty [at] yahoo [dot] com)

This bridge is scheduled for replacement with a higher fixed bridge viaduct by SCDOT. Construction should begin in the Fall of 2017 and will take approximately three years at an estimated cost of $56 million dollars.

There is a local movement to try and save the bridge, but struggle to find any real historical significance to the old swing bridge. SC has nine moveable bridges, but doubt this is remarkable enough to save from replacement especially since federal funding has been established and the planning and engineering phase was completed in 2014.
